Abstract
Studies have confirmed that many moisture problems in houses are caused by penetration into the walls of warm, moist househould air. Air leakage can be conteolled by installing an air barrier sytstem that meets four requirements: it should be air impermeable, structural or rigid, continuous, and durable or maintainable. Types of air leakage include diffuse flow andorifice flow. The most damaging is channel flow, which leaves moisture in walls. A computer program has been developed that can determine maximum leakage levels for avariety of wall assemblies and climates. This paper provides tables and descriptions of air leakage rates of selected building materials and tests of wind resistance of air barrier systems for wood frame walls. With airtight materials and developed technology, we can produce airtight buildings.
